It is used to define the structure and layout of a React component
It is used to handle asynchronous operations and data fetching
It is used as a wrapper to render multiple elements without adding extra nodes to the DOM
None of the above
By using the "try-catch" block in the component's render method
By using the "componentDidCatch" lifecycle method to catch and handle errors
By using global error handling provided by the browser

Controlled components rely on state for managing their data, while uncontrolled components do not.
Controlled components allow user input to directly update the component's state, while uncontrolled components do not.
Controlled components are created using classes, while uncontrolled components are created using functions.
